How to bank in foreign currency checks in Hong Kong at a low fee

I have some foreign currency checks. How to deposit them to my Hong Kong account in Hong Kong at a low fee?

I have accounts on several banks in Hong Kong. If possible, I would like to open more for banking in foreign checks if they are better for this purpose than other banks.

Fee for receiving US$250:

Hang Seng Bank: HK$ 60
Bank of China, Hong Kong: HK$ 70
PayPal: HK$78

Hence, Hang Seng Bank seems charge least among these 3.
